If the conduit is un-coated you may want to do so.Paint, or foam pipe insulation, piece of plastic bag. Don't want have to replace it down the road because of the concrete corrosion.

The sub floor conduit is the correct schedule PVC pipe for electric use. The pipe runs convert to steel at the elbow where it comes up through the concrete. The pipes were set by digging a small trench in the stone/dirt floor and laying in a bed of sand. The pipe was then covered with the sand and smoothed over while the steel elbows and risers were clamped to the wall. After the pipe work was complete, sheets of poly/plastic were placed over the entire stone/dirt floor. The concrete does not contact the PVC pipe, only the steel elbow and riser pipes that feed up to the outlets. The system was designed by WW&F member and master electrician Josh Recave who does most of the museum's electrical work.

Figured that was the prob. That's one situation we don't have much here in East Abq at 5500' with <10-inch annual rain, maybe downtown by the mighty 3-foot deep Rio Grande lined with narrow bosques (wooded strips).

* The new floor must remain clean, sealer coating will be applied either Friday or Saturday.

* No rolling stock of any kind in bay 2 & 3 for 30 days.

* No connecting yard tracks to the bay 2 & 3 rails until further notice. Be careful moving things around the north end of the shop so you don't hit the ends of the bay 2 & 3 rails that extend out of the back.

We have a nice new floor that with care and a bit more work to get it ready will give many years of service to the railroad.

One concrete floor.Questions...*looks like the vapor barrier, usually the first to be laid, is above? the WWF mesh, which itself needs support to half the depth of the slab for proper reinforcement.*when will the flangeway blockouts come out? Hope they were oiled.*slab finish looks rough, will make it harder to keep clean.*no construction joints? Concrete cracks, wherever, whenever it wants.

Slab sealing is definitely needed.And of course, treat that slab like it is radioactive, until mid-October!!

Take note at the third and sixth pictures. The wire mesh is clearly above the vapor barrier. Usually rakes are hooked under the wire to pull it up to mid concrete as the pour progresses. Note the guy in the white tee shirt in the sixth picture. He appears to have the rake in his hand.
